Frequently asked questions

Quick answers about Dockera and our tools.

How to resize image to 100KB?

Use our Resize Image tool: upload your photo, select 100KB as the target size, and click Resize. The tool runs in your browser and outputs a file under 100KB. You can also choose 20KB or 50KB for stricter form limits.

Is Dockera safe?

Yes. Dockera is designed for privacy. Processing runs in your browser where possible, and we don't store your files. No sign-up is required to use the tools.

Do files get uploaded?

For the resize, compress and signature tools, processing happens locally on your device. Your files never leave your device unless a specific tool clearly states otherwise.

What formats are supported?

We support common image formats (JPEG, PNG, WebP) for resizing and passport photos, and PDF for compression. Outputs are in standard formats accepted by most portals and forms.
